I am using the June build of Pex from MSDN on an x86 Windows XP box.

Installing SlimDX SDK from June 2010 causes Pex to no longer run within VS2010. Pex wouldn't run explorations even if there are no references to SlimDX in my C# project. I reproduced this on a friend's PC.

Uninstalling SlimDX June 2010 fixes the issue.

How can I get latest of Pex and latest of SlimDX to work together?

P.S. This question also lives on Microsoft forums:
